Title: Digital data processing system
Inventor: CHI-CHUNG WONG ANDREW
IPC: G06F17/14
Filed: 1981-11-12
Abstract: The technique of breaking up a binary coded array of input data points into a plurality of one-bit precision sub-arrays of shorter address length and of different significance, and mapping the sub-arrays sequentially into output data points in a look-up operation, the output data words then being individually weighted according to the significance of the sub-array before being re-combined, is extended to a multi-stage "butterfly" structure, in which an n-point Fourier transform is split into the sum of m<n>m-point transforms. The sequences of sub-arrays are interleaved into m blocks, and the interleaved arrays sequentially address a corresponding number of memory blocks in a first stage of the multi-stage structure, each block having a look-up table for mapping the sub-arrays into respective output points, and the phase rotation between the output points of the second and subsequent blocks with respect to the phase of the output points for the first block being inherent in the look-up tables of the second and subsequent blocks. <IMAGE>

Title: Traveling-wire electroerosion machining electrode and method of using it
IPC: B23H7/08
Filed: 1981-11-18
Abstract: A travelling wire electrode comprises an elongated element having a thickness of 0.05 to 0.5 mm and an irregular surface. The machining gap is flooded with a machining liquid directed along the electrode from a chamber surrounding the electrode and the nature of the surface helps it to shed gaseous bubbles formed by the electrical decomposition of the liquid which tend to adhere to the electrode and thus act as a thermal insulator between the electrode and the coolant machining liquid. Various ways of producing the irregular surface are described: e.g.- forming projections 63a and recesses 63b in a regular pattern on a cylindrical wire surface; twisting together a group of small diameter wires; winding a small diameter wire on a larger diameter core wire; and forming a spiral groove in the smooth surface of a wire by means of a rotating die. <IMAGE>

Title: Mobile storage system
Inventor: YANASE KENZO
IPC: A47B53/02
Filed: 1983-02-08
Abstract: A mobile storage system having a plurality of mobile stacks (13a, 13b, ...) and a stationary stack (12). The stationary stack (12) has a pushbutton switch (15) and a control circuit, whereas the mobile stacks (13a, 13b, ...) have pushbutton switches (16a, 16b,...) and control circuits respectively. The pushbutton switches (15, 16a, 16b,...) are arranged to open an aisle or access passage. The mobile stacks (13a, 13b,...) have reversible motors (14a, 14b,... ) to shift the respective mobile stacks (13a, 13b,...) to the right or left. The control circuits have memories which store data indicating stack numbers, respectively. When an operator depresses one of the pushbutton switches (15, 16a, 16b,...), data is read out from the corresponding memory and is transmitted to the rest of the control circuits through a common data bus. The common data bus connects the stationary and mobile stacks (12, 13a, 13b,...). The control circuits of the mobile stacks compare the data transmitted through the common data bus and data stored therein, thereby determining the required shift direction of the stacks so as to drive the motors (14a, 14b, ...) and hence to shift the mobile stacks (13a, 13b,...). <IMAGE>

Inventor: VINCENT MARTIN PAUL
IPC: F16H3/12
Filed: 1984-02-28
Abstract: In a tractor power take-off mechanism comprising an input shaft 60 driveable from an engine by a friction clutch and a two-speed power take-off shaft 61 driveable from the input shaft 60 by gearing 62-65 including a disengageable toothed driving member 66 operable by a hand lever 81 by way of a selector fork 68, the disengageable toothed driving member 66 can be difficult and noisy to engage because the input shaft 60 tends to rotate due to inertia and drag when the friction clutch is disengaged. The input shaft 60 is therefore provided with a hand brake 86 applied by initial movement of the hand lever 81 in a direction to engage the disengageable toothed driving member 66 and held applied whilst an operating load is being exerted on the lever 81 in that direction. A conventional detent 71 holding the selector fork 68 in disengaged position provides the resistance required to cause the brake 86 to be applied before the lever 81 can move the fork 68 into engaged position. <IMAGE>
